KENT, OF WASHINGTON, DISTRICT OF COLUMBI VACUUM CLEANING-TOOL Specification of Original application filed September 24, 1912, Serial No. 722,141. Divided and this 25,1913. Serial No. 756,765.

Letters Patent.

application filed March To all whom it may concern Be it known that I, EUGENE M. KENT, a citizen of the United States, and resident of Rome, county of Oneida, State of New York, have invented certain new and useful Improvements in Vacuum Cleaning: Tools, of which the following is a specification.

This invention relates to vacuum cleaning apparatus and more particularly to tools for cleanin carpets, rugs, etc.

This app ication is a division of my prlor application No. 722,141, filed September 24, 1912.

Some of the objects of the invention are to provide a tool adapted to permit a more or less uniform flow of air, and in which the nap of the carpet through which the an is passing, isperfectly free and not held down by the tool, so that the air Wlll agitate the nap and so loosen and lift the fibers thereof that it can penetrate to the warp with suflicient force to remove any dirt or dust which may have accumulated thereon.

Other objects and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings in which- Figure l is a perspective view of a tool embodying the invention, and Fig. 2 1s a central vertical section of the same.

Referring to the drawings, 19 indicates the usual elongated casing or body havlng an air inlet 25 in the lower side thereof adjacent'the surface to be cleaned. A suction pipe or tube 12 is connected with the upper part of the casing in any suitable manner as by'the threaded collar 13, this collar permitting the casing to swivel or oscillate onthe pipe as the tool is moved to and fro over the surface to be cleaned.

A shoe having front and rear walls 20 and 24*, respectively, surrounds the lower end of the casing 19 and is preferably formed integral therewith or otherwise fitted thereto at its ends. I The shoe rests on the carpet or surface to be cleaned, as clearly shown in Fig. 2, and supports the casing 19 with the lower edges 21 and 22 of the latter sli htly above the carpet or surface. The front wall 20 of the shoe is spaced from the casing to provide a downwardly directed air inlet 23 which extends substantially the full length of the casing. This air inlet may be of any suitable cross-section. The rear wall 24 of the shoe is similarly spaced from the rear wall of the casing to provide the air inlet 24 which also extends substantially the full length of the casing. It will be observed that the inlets 23and 24 are in downwardly converging relation and the air currents entering through these inlets are made to unite in a rising current which flows through the caslng'inlet 25.

In the operation of the tool it is moved over the carpet or surface to be cleaned and the air, bein drawn throu h the inlets 23 and 24 into t e interior of t e casing 19, by the suction in the pipe 12, will be projected with considerable force against the surface being cleaned, directly below the lower edges 21 and 22 of the walls of the casing, and thoroughly scour the surfaceand car away the dirt therefrom. When the tool is used on a carpet or rug having a nap or pile, as indicated in Fig. 2, the distance between the front and rear walls 20 and24 of the shoe permits the nap underthe casing'19 to be free so that the currents of air through the inlets 23 and 24, instriking the carpet, will penetrate to the war thereof and in rising to the inlet 25, will ift up the nap and so loosen and agitate it that the dirt clinging thereto will be removed and the dirt accumulated on the warp may be readily carried-up through the nap by the air. As the tool moves over the carpet the walls of the shoe smooth out the nap and the carpet is given a bright, sleek appearance.

Having thus described my invention what I claim is 1. A vacuum cleaning tool comprising a casing having a long narrow inlet slot in its lower side, a suction pipe connection, a shoe fixed to the casing and provided with meansv in the front and rear of said slot adapted to engage the surface to be cleaned andsupport the lower edges of the front and rear walls of the casing slightly above said surface whereby air passages are provided beneath the casing walls, said means being spaced respectively from the front and rear walls of the casing and forming with the casing walls downwardly directed air passages adapted to supply air to the casing inlet from opposite sides of the latter.

2. A vacuum cleaning tool comprising a PatentedJune 2, 1914.

n being spaced respectively from the front and rear walls of the casing to provide relatively converging downwardly directed air inlets adapted to supply air to the casing inlet from opposite sides of the latter.

In testimony whereof I affix my signature '15 in presence of two witnesses.
